DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 7 thereof, a new heated stand mixer device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 7, the stand mixer and heating means combination apparatus 10 generally comprises a stand mixer 12 that has a base 14, a post 16 attached to and extending upwardly from the base 14, and a mixer housing 18 is pivotally coupled to the post 16 opposite the base 14. Mixing attachments 20 are attachable to the mixer housing 18 and rotated by the mixer housing 18 when the stand mixer 12 is turned on. The above stand mixer 12 is conventional in function and includes a motor 22 and motor control 24. The stand mixer 12 also includes a power cord 26 for supplying electrical power to the stand mixer 12. The power cord 26 may be a retracting cord. A top side 28 of the base 14 includes a container mating member 30.
An outer container 32 has an outer surface 34 that has a mixer mating member 36, which is releasably engageable with the container mating member 28. The mixer mating member 36 engages the container mating member 30 such that rotation of the mixing attachments 20 does not decouple the outer container 32 from the base 14. The outer container 32 includes a bottom wall 38 and a perimeter wall 40 that is attached to and extends upwardly from the bottom wall 38. The outer container 32 may be comprised of any conventional material used for cooking purposes and may further have measuring indicia thereon indicating volume increments within the outer container 32.
A heating assembly 42 is mounted on the top side 28 of the base 14 and is spaced from post 16 and below the mixer housing 18. The heating assembly 42 is in thermal communication with the outer container 32 when the mixer mating member 36 is engaged with the container mating member 30. The heating assembly 42 heats the outer container 32 when the heating assembly 42 is turned on. The heating assembly 42 may comprise any conventional heating means such as an electric heating element, hot plate, an induction heating assembly, and the like. The heating assembly 42 will likely extend above a plane of the top side 28 to allow the heating assembly 42 to be used as a conventional electric cook top for heating pots and pans for conventional cooking purposes. An actuator 44 is mounted on the stand mixer 12 and is electrically coupled to the heating assembly 42 to selectively turn the heating assembly on or off. The actuator 44 will include different temperature settings 46 and may further include a timer 48 to shut the heating assembly 42 off at a selected amounted of time. The heating assembly 42 will likely include a safety sensor to turn off the heating assembly should the heating assembly 42 become overly heated. The actuator 44 may further be in communication with the mixer motor 22 to cut power to the mixer motor 22 after a specified amount of time.
An inner container 50 has a lower wall 52 and a perimeter wall 54 that is attached to and extends upwardly from the lower wall 52. The inner container 50 has a size to be positioned in the outer container 32. The inner container 50 may also be comprised of any conventional cooking material and may again include measurement indicia therein to indicate an internal volume, at different levels, of the inner container 50. A handle 56 or grip may be attached to the inner container 50 and positioned adjacent to an upper edge of the perimeter wall 54. An outer container 36 handle 57 may be incorporated as well. Each of the outer 36 and inner 50 containers may also be equipped with removable lids, not shown.
A first mating member 58 is attached to an outer surface of the inner container 50 and a second mating member 60 is attached to an inner surface of the outer container 32. The first 58 and second 60 mating members are releasably engageable with each other to secure the outer 32 and inner 50 containers together while retaining the lower 52 and bottom 38 walls in a spaced relationship with each other. The first 58 and second 60 mating members are also configured to prevent the outer 32 and inner 50 containers from being dislodged from each other by the rotation of the mixing attachments 20. A space between the inner 50 and outer 32 containers is in communication with air outside of the outer container 32 when the inner 50 and outer 32 containers are attached together to allow release of steam. This allows the outer 32 and inner 50 containers to be used as a double boiler wherein water that is positioned between the outer 32 and inner 50 containers is heated when the outer container 32 is heated by the heating assembly 42. The water in turn heats the inner container 50 but in a controlled manner which prevents the burning of food contained within the inner container 50. Alternatively, the inner container 50 may also be perforated so that food within the inner container 50 may be steamed by the boiling of water in the outer container 32. In such an instance, the inner container 50 will have a lower wall 52 spaced at least 5 cm from the bottom wall 38 of the outer container 32. Finally, one type of food may be boiled in the outer container 32 while the inner container 50 is being used to cook a second type of food. Again, this would require sufficient space between the lower 52 and bottom 38 walls to accommodate food and water therebetween.
A water indicating assembly 62 is mounted on the stand mixer 12. The water indicating assembly 62 is configured to signal a person to verify water is positioned between the inner 50 and outer 32 containers when the inner 50 and outer 32 containers are being utilized as a double boiler. The water indicating assembly 62 may be configured in a variety of forms. One form may include a water timer. The water timer actuates an alarm after a predetermined amount of time has elapsed which corresponds to a typical amount of time passage at which point the water level becomes too low. The alarm may include a light emitter 64, an audible alarm sound utilizing a sound emitter 66 or a combination of both. In particular, water will be placed in the outer container 32 to a predetermined level which corresponds to the predetermined amount of time. When the alarm is actuated, the user of the apparatus 10 will understand that the water levels much be checked and refilled if necessary. Another form of water indicating assembly 62 may include a fluid probe embedded in the outer container 32 which electrically engages the stand mixer 12 when the mixer mating member 36 and the bowl mating member 30 engage each other. When the water level becomes too low to be detected by the probe, the alarm will be actuated. Yet another form may utilize the water for closing a circuit between the outer 32 and inner 50 bowls wherein lower water opens the circuit to actuate the alarm.
In use, the stand mixer 12 may be used in a conventional manner to mix food. However, when the food is to be heated, the heating assembly 42 is turned on to cook or heat the food while it is being mixed. The ability to use the outer 32 and inner 50 containers together, however, allows a person to cook what are typically labor intensive foods automatically. Preparations of certain foods such as custards, sauces, jams, risotto, confections and the like require frequent mixing over a prolonged period while heat is applied to the food. The apparatus 10 allows a person to simply add the ingredients and turn the apparatus 10 on so that it mixes the food while it is being heated. The use of a double boiler type apparatus will ensure that the food in the inner container 32 will be evenly and steadily heated. The actuator 44 may also be programmed with recipes for particular foods which not only controls the mixing motor 22 but which also controls and varies the amount of heat being used. This will allow a person to set the apparatus to make the pre-programmed recipe and return to the apparatus when it is finished.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
